How to Validate a Word DocX using Java

2 min readJun 21, 2022


If your website/app is handling a lot of Microsoft Word (DocX) uploads, you should include a validation process to ensure the document works correctly before storing that data in your database. You can easily do so by including our DocX Validation API, which will quickly identify any errors in an invalid DocX document and report those errors instantaneously. Below, we’ve provided complementary code examples to help you structure a call to this API so you can easily incorporate this service into your app for free.

Let’s start by installing the Java SDK with Maven. First, add a reference to the pom.xml repository:


Next, let’s include the following reference in the pom.xml dependency:


Lastly, we can include the import classes and call the API. Make sure to have your DocX file and your Cloudmersive API key (obtainable by registering a free account on our website) handy:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.ValidateDocumentApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
ValidateDocumentApi apiInstance = new ValidateDocumentApi();
File inputFile = new File("/path/to/inputfile"); // File | Input file to perform the operation on.
try {
DocumentValidationResult result = apiInstance.validateDocumentDocxValidation(inputFile);
} catch (ApiException e) {
System.err.println("Exception when calling ValidateDocumentApi#validateDocumentDocxValidation");

All done — no further code required.




There’s an API for that. Cloudmersive is a leader in Highly Scalable Cloud APIs.
